Abstract

Le dispositif (10) de capture d'image thermique comporte : - une caméra thermique (22) fournissant successivement des images thermiques non compensées des variations de réponses des pixels du capteur ni des différences de température de la caméra, - un circuit (24) de détermination de différences, pixel par pixel, entre deux images successivement fournies par la caméra, fournissant une image de différences et - un circuit (26) de transmission à distance de l'image de différences. Dans des modes de réalisation, le dispositif de capture comporte, de plus, un circuit (29) de compression de l'image de différences, par exemple pour binariser l'image de différences. Préférentiellement, le dispositif comporte un support (20) de caméra entouré par un tube (14) protégeant du vent le support de caméra.The thermal image capture device (10) comprises: - a thermal camera (22) successively supplying uncompensated thermal images of the sensor pixel response variations and the temperature differences of the camera, - a circuit (24) of determining differences, pixel by pixel, between two images successively provided by the camera, providing an image of differences and - a circuit (26) for remote transmission of the difference image. In embodiments, the capture device further includes a difference image compression circuit (29), for example to binarize the difference image. Preferably, the device comprises a camera support (20) surrounded by a tube (14) protecting the camera support from the wind.
